NAME

       CURLOPT_KRBLEVEL - FTP kerberos security level

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_KRBLEVEL, char *level);

DESCRIPTION

       Pass  a  char  pointer  as  parameter.  Set the kerberos security level for FTP; this also
       enables kerberos awareness. This is a string that  should  match  one  of  the  following:
       &'clear',  &'safe', &'confidential' or &'private'. If the string is set but does not match
       one of these, 'private' is used. Set the string to NULL to disable  kerberos  support  for
       FTP.

       The application does not have to keep the string around after setting this option.

DEFAULT

       NULL
